  • Receiving and measuring expelled gas from a core sample
    Patent number: 9482089
    Abstract: An example system for receiving gas expelled from a core sample of a formation may include a tubular element. A core chamber may be disposed within the first tubular element. A gas and drilling fluid separator may be in fluid communication with the core chamber. The tubular element may be an inner barrel assembly of a core sample assembly that is disposed within a borehole. A core sample may be contained within the inner barrel assembly and may be retrieved at the surface. Gas may be expelled from the core sample as it is retrieved, and the gas and drilling fluid separator may separate the expelled gas from suspension with a drilling fluid for analysis.

  • Near-Bit Borehole Opener Tool and Method of Reaming
    Publication number: 20150226009
    Abstract: The present disclosure relates to a near-bit borehole opener (reamer) tool and a method of drilling a wellbore comprising: (a) disposing in the wellbore a tool string; (b) lowering and rotating the tool string and drilling a first portion of the wellbore having a first diameter with the drill bit, wherein the at least one cutter assembly of the borehole reamer is in a closed position; (c) reaming with the second borehole reamer a portion of the wellbore to a second diameter larger than the first diameter, wherein a rat hole portion of the wellbore is not reamed with the second borehole reamer, said rat hole portion of the wellbore having the first diameter; (d) extending the at least one cutter assembly of the first borehole reamer; and (e) concurrently rotating and moving the first borehole reamer up or down in the rat hole portion of the wellbore with the first diameter and abrading and cutting away the wellbore wall contacted by the at least one cutter assembly of the first borehole reamer assembly, thereb
